A good choice, but check the underground material spec. first. If they are using C900, there is really no need to have a dielectric flg. or union.
Also determine the purpose of the isolation. If it's Dept. of Defense, or one of the many alphabet soup names, the issue may be more than simple isolation, and require transmission frequency alteration. Water is a very good conductor of sound, ask any submariner. To protect verbal communication they may be wanting to induce "Noise" to prevent covert listening.
